[WP-34S] My first integral on this calculator
Hi all,
I managed to run my first integral on my new WP-34S! I must say that, despite using HP RPN calculators since the 70's, I quit using calculators for many years, and only recently started to look again to these devices, by acquiring the 49+, 48GII, 50G and Prime. So I have missed the HP-15C and 42S series and I was not aware on how to use integrals in these machines. As the WP-34S is loosely based in the HP-15C and 42S machines, I had to spend some time digging it until I could use the WP-34S as I intended. I was expecting the WP-34S to be more closer to the 42S than to the 15C, but it seems that this is not the case. So I took this example where a simple integral is used to compute the "angle of twist" problem from page 125 of the HP-42S Programming Examples guide, and have adapted that HP-42S program code to run in the WP-34S but using the HP-15C style (so, no local variables at all). I know this is basic stuff for HP-15C / 42S experts, but I believe that probably more people will have the same questions as I had when I tried to take a simple integral in this excellent RPN WP-34S (for me it so much easier to do it using "pretty print"/"equation editors"/"templates" as I do on my HP-Prime, 50G, and even on a Casio FX-991DE Plus...!). To invoke the integral: 1. Create the program and name it 'TOR' 2. Load the lower and upper limits Limits (in this example, Lower (Y):0 Upper (X):2 3. Invoke it from the entry mode: h + 2 ENTER TOR WP-34S result: 0.02805957296 (HP-42S result as stated in the guide: 0.0281) Time to complete: about 5 seconds My WP-34S program code for the "Angle of twist" problem: LBL'TOR' 1 3 * 8 + * 1 5 + * 9 + * 6 + 7 . 9 5 2 1 EEX 8 +/- / 8 3 EEX 9 / RTN END Jose Mesquita RadioMuseum.org member |
